Veg in greenhouse

[Polycarbclare]

Evening all. I joined this site yesterday and loving all the forums. Im sorry if
I'm asking simple questions on the wrong forum. Please can someone help. The veg I plan on growing in my polycarb greenhouse are tomatoes peppers onions chillies lettuce cucumber some
Fruit maybe strawberries etc. can all these items once established remain in large pots in the greenhouse and continue to produce good crops

If you plan to spend a lot of money through the autumn/winter heating and providing extra light for your greenhouse, then yes a few of those will keep on producing

but most people in the uk forgo trying to keep this years plants alive and start off new ones early next year

Hi and welcome to the madhouse. Heating a greenhouse makes a huge dint in the pocket and in my mind not worth it for growing veg... But starting plants off early in a cool greenhouse for planting out when conditions are right is what I do. One year a did grow an early crop of peas in the greenhouse and they did ok. This year I have a container full of leeks that I am going to keep growing all winter for spring use. I suppose you could also grow winter and spring cabbage in containers in the greenhouse.
Try a few plants and see what happens.

Now I read the original post quite differently... I thought the query was more about whether the plants would survive the growing season in large pots, or whether they'd need to be planted in beds.. Anyway.. they'll all grow quite happily in pots during the growing season as others have said, but not worth trying to keep most of those specific crops going over winter if that's what you were asking. Except possibly the onions, which you'd be planting around now for next year, and the strawberries which will be fine in big pots. I have straws in a raised bed in my polytunnel and they crop early and well . Don't forget that you'll need to water and feed things in pots more regularly than in a bed .

As Kathyd says, this depends what you are asking. I'd make a strong case for overwintering broad beans in large bags in the poly. They will crop much earlier than outside, don't get destroyed by the wind and provide an early feed for bees.

Spring cabbage such as Flowers of Spring/Precoce de Louviers will do well in deep pots if not overcrowded (ie they need air movement around each plant).

Why don't you introduce yourself on the Intro thread and tell us a bit more about yourself there. Glad to see you put your location in so, "Croeso".

For growing now or next year?
This year you might get a decent crop of lettuce and if you got a winter variety of onion, but the others you mentioned I don't think they would have a chance.
Excluding the peppers and strawberry I have the others growing in my greenhouse at the moment and they all are doing well.
I've never had much luck with onions (only bother with spring onions inside) in a greenhouse as they tend to bulb too quickly still worth the hassle, but not as good as slightly slower grown ones outside.

I've just started sowing my winter veg for the greenhouse which consists of oriental greens, mustards and kale.

O and as for the pot size chills are in 7l flower buckets as are the spring onions. Tomatoes, cucumber and lettuce are in 2'x4'x1' (width, length, depth) troughs.

onions lettuce strawberries

They'll do better outside. Greenhouses, unless they are very large and well ventilated, are generally too hot for those crops.
A polytunnel would be better, because it's less hot and more ventilated, but with the added protection from wind & frost

Thank you all for your advice. All the crops I mentioned I want to start growing next year. Just trying to pick up as much advice as we can.

As two_sheds says.

Though you could probably give the others a head start in the greenhouse early next year, or even get some onions started before christmas so they are ready to plant out next spring. Or do some lettuce over the winter.....

and..... Hello from down the road.
